zo claims.' y(ci. 141-7) A The invention relates tor an improvement inmachines for Washing cans and the like, and more particularly to animprovement in machines for washing, sterilizing and drying therelatively large cans used for transporting fresh milk from the point ofproduction to the receiving and treating stations.

. Can washing machines are usually of two general types: a longitudinaltype in which a can transporting Ycarriage moves longitudinally topresent the cans to the can cleansing elements,

which are arranged in a straight line; and a roo tary type in. which thecan transporting carriage travels in a circular path to present the cansto the can cleansing elements,'which are arranged in a circle.

The general object of theinvention is to'produce a can washing machineof the rotary type which is cheaper to build; and operate, is smaller,more compact and composed of fewer parts, and is more emcient anddurable than such can washing machines as heretofore constructed orpro-` posed. I

.In the machineof lthe present invention there is provided a rotary'carriage or turntable which carries a number of cans in invertedposition and holds them successivelyover each of a series of nozzleswhich subject the cans to cleansing treatments. The rotary carriage ismoved witha vertical movement aswell as with an intermittent rotarymovement, so that it lifts a-can from posi- ,tion over one nozzle, thenby a rotary movementconveys the can to position above the next nozzleand then descends to lower the can so that the nozzle above which it issituated projects into the can and directs the cleansingiiuid thereinto.this cycle of operations, each can is carried from one nozzle to thenext and after the cleansingv treatments are completed, the can isejected,

right side up, from the machine.

The inventionvalso includes the provision of means for subjecting thecan' covers to cleansing treatments similar tothose received by the cansand simultaneously with the cans so that when each can is ejected fromthe machine? its cover will also be ejected and will fall into the mouthf of the ejected can and `be carried away thereby.

A novel feature of Vthe inventionconsists in the means which directseach cover into a rack located on the can carriage above the compartment in which the can to which the cover belongs is positioned. The rackholds the covers in position to be treated by iiuids directed fromnozzles operated simultaneously with-the cantreating nozzles.

Another novel feature of the invention resides` A in the means by whichthe cove'rs are ejected from the can carriage and then directed intothe.

mouths of their corresponding cans as they leave the machine.

l 'I'he present invention comprises other novelr features, theadvantages of vwhich will be pointed out as the description proceeds,the improved machine of the invention being fully described .I

hereinafter and the novel features thereof being particularly pointedout in the appended claims.

The improved can-washing machine is provided with a stationary framevcomprising the four uprights 25, connected yat their upper ends by twospaced horizontal bars 25 and near their lower ends by the horizontalbars 21; The frame thus formed is braced at its lower end by crossmembers 21a which connect the uprights 25, as shown in Fig. 4, and atits upper end by cross braces 25a which connect the upper ends of theuprights 25, as seen in Fig. 1. Supported at the lower part of the frameare tanks 28, 29, 30, 3|,

32 and 33 over each of which (with the exception f of the tank 28, whichis merely a drip pan) is located aL nozzle for subjecting the interiorof a can held over it by the can carriage, to a cleansing The firstnozzle to which a can is presented. is shown at 34, and it subjects thecan to a cold water rinse. The second nozzle 35 rinses the interior ofthe can with hot water; the third nozzle 35 directs a cleansing solutionagainst the inner surfaces of the can; and the fourth nozzle 31 washesthe inner surfaces of the can with clean hot water. Nozzle 38 subjectsthe interior of the can to a steam bath and nozzles 33 and 48 direct astream of cold air into the can to dry it. While these nozzles arecleaning the interior surfaces of the cans, jets located adjacent to theVnozzles 34, 35, and 35 clean the outside surfaces of the cans, andanother series of nozzles shown at |23 (Fig. 1) cleanse the can coverscarried by the can carriage in Acompany with the The can carriage orturn-table, which is rotated clockwise when viewed in plan and whichcarries the cans successively from one nozzle to the next, is raised andlowered vertically and is also intermittently rotated about a centrallylocated vertical shaft 4| having its lower end mounted in bearings 42and 43. and its upper end mounted in a bearing 44 which is formed on orsecured to a cross-piece 45 connecting the two spaced upper framemembers 25,A as shown in The lower bearing 42 is secured on top partingthe vertical movement to the carriage is located. Bearing 43 is formedon the lower plate 'or body 41 `(Fig. 20) of the casing, which issupported upon the two lower cross bars 21 of the machine frame. .l

A sleeve 48 forming the central parto! the can carriage is mounted tomove vertically and rotatably on the shaft 4|. The sleeve is providedwith a collar 48 from which a pluralityV of brace` members 5|) radiate.At theirV outer ends, these radial braces 58 connect with an octagonallyshaped frame or cage composed of eight lower angle bars 5|, eight upperangle bars 52 and eight connecting vertical braces 53. Near its upperend the sleeve 45 is provided with a collar 54 from which extend radialbraces .55 connecting the sleeve with the cage composed of the elements5|, 52 and 53.

Extending radially from the upper .and lower carriage frame members 5|and 52 are horizontal 5| by the pieces 58 (Fig. 18). -rangement anoctagonal carriage frame is proangle irons 55.` Prom the lower framemembers 5| angle irons'51, forming the can supports, also projectradially. The ends of the members -51 are connected to the ends of thelower members Through this arover and covers the tops of all of the cancom-` partments.

'I'he can carriage or turn-table 'is driven with an intermittent rotarymovement from the ver-l tical shaft 4| which is provided at its lowerend with a large gear 52 located within the gear Y casing composed' ofthe casing elements ,45 and 41. Gear 52 is driven by a pinion53 securedona shaft 54 rotatably mounted in the gear casing andlcarrying a bevelgear 55 which meshes with another bevel gear 55 secured on a shaft 51mounted in the bearing 58 secured on one of the lower frame braces 21a.yThe shaft 51 is driven by a motor or othersuitable source of power. Atits upper end, the vertical shaft 4| carries an arm 59 (of a Genevamovement) provided with a roller on its end arranged to enter the slotsof a wheel 18 which is secured upona short shaft 1| rotatably mountediin bearings 12 and 13 sup-A ported on cross-pieces 14 and 15 supportedon the top bars 25 of the machine frame. 'Ihe shaft 1| carries a gear1,5 .which meshes with a gear 11 free on the vertical shaft 4| andsupported thereon by the collar 15 pinned to the shaft 4|.

Secured to the gear 11 is an arm 15 provided at its outer end witha-downwardly projecting pin `8|l located in the slotted end of a fork5|' secured ,l at the upper end of the sleeve 48. Through this drivemechanism it will be apparent that the..

carriage is intermittently rotated to locate cans carried by it invertical alignment with the nozzles during pauses in the rotativemovement of the carriage. The rotation ofthe can carriage occurs onlywhen the carriage Iis in its elevated position, in which position thecarriage is raised clear of the nozzles, as shown in Fig. 3. During thedescent of the carriage and while the cans are over the nozzles duringthe injection of cleansing uids into the cans,'no rotarymovement. of thecarriage occurs. l

The large gear 52 operates the mechanism for raising andv lowering thecan carriage, such mechanism being shown in detail in Figs. 19.to Thegear 52 is provided with a cam groove 52 in which a roll 53 on the endof an arm 54 (Fig.r21) is located. Arm 54 is secured on a pivot pin 55journalled inthe gear easing elements 45 and 41 and another arm 55positioned over theaarm 54 is secured on the pivot pin '85 above thegear easing cover 46.' The end of the arm 55 is pivotally connected toone endof a cover 45. The longer arm 3| oi' the bellcrank 75 pended froma cable 98 extending over pulleys 99v and 99a and connected with the endof the arm the cans when they are manually placed in inverted positionon the platform. In Fig. 13,is v

the top of its inner end and arranged to project under the lowerend 95of the sleeve I8. .as the roll 83 is moved to the left, viewing Fig.`19, by

the action of the cam groove 82, the lever.

acting through the link 88a, draws thearm 81 of the bell-crank lever tothe left, causing the l longer4 arm 9| thereof to be swung upwardly tolift the sleeve 48 and-elevate the can carriage supported thereby; Thecan carriage is counterbalanced by alweight 96 so that it will rise anddescend smoothly. 'I'his weight 95 is movable" vertically in a vguidetube 91 supported by the` machine lframe bars 25 and 21a, and is` sus-9|of the bell-crank lever.

bars 51 of the carriage from a stationary entrance platform |00, shownin detail in Figs. 6, 14 and 18. The platform is in the form of a gridto permit the drainage of any milk residue from shown an inverted can onthe platform in position to be pushed ontoy the can supports of thecarriage.

The outer end of the platform is reotangularly shaped and.is locatedoutside of themachlne, and the inner narrowed end of the platformextends into-the machine and is located over the tank or drip pan 28. Atits inner end the platform is supported on a cross member 211 extendingacross the tank 28, Aat'an intermediate point by an angle iron 218 (Fig.13) attached at one edge of the tank, and at its outer end byI theYbrace 219 extending outwardly from the tank 28. The outer part of theplatform has a guard j carriage, or in the direction of thel arrow inFig.

flange 215 extending along one of its longitudinal edges and a shorterguard flange 216 extending Valong apart of the inner end of its oppositeedge.

51 lifting the can from the' inner end of the platform and carrying itto'position over the nozzles successively.

In placing a can on the carriage, the can is first stood in invertedposition on the outer end of the platform and slid inwardly toward the-13. I f the carriage is in its raised position when the can is slidalong the platform, the edge of the mouth of the can will strike a stopmember |02 projecting upwardly through the 4platform. The stop |02 isthe upwardly-extending end of a lever |03 pivoted at |04 on the tank 28.The

. other end of the lever is connected to a spring |05 fastened to a pin|08. When the stop is projecting upwardly through the platform itprevents farther-sliding movement of the can toward the carriage untilthe carriage descends and reaches its lowered position in readiness toreceive a can from the platform. One of the can supports 51 then strikesan o-set arm |01 extending inwardly from the lever |08 thereby forcingthe stop |02 downward belowthe platform so that the can resting thereoncan .thenv .be slid inwardly along the platform until `it l reaches aposition on the narrowed end |0| thereof. as shown in dotted lines inFigs. 13 and 18. In this position the mouth of the can will be over onepair of can supports v51 of the carriage, but Anot actually onthem-because when the carriage reaches its lowest position of descent,the supports 51 are below the upper face of the inner end of theplatform. Thiswill be clear from Figs. 13 and 15 where the can is shownresting `on the .inner portion |0| of the piatform with the cansupportsl 51 located below the mouth of the can. Each pair of cansupports 51 is` connected bya cross brace |08 which cooperates with thesupports 51 in carrying the can and which on the descent of the carriageenters into a transverse groove |09 in the upper face of the platform.-When the'carriage rises.

rotated sufficiently to locate the can carried by it above the firstnozzle`34, and it then descends until the nozzle projects within thecan, so that the cold water issuing from the nozzle will spray theinterior surfaces of the can. When the can is slid alonguthe platform`|00 When the `carriage o toward the carriage preparatory to beingdelivered thereto, the forward side of the can strikes an arm ||0secured on and projecting from a verticali shaft located in each cancompart- Iment and pivoted in the plate |30 andl i'n the The lower endof frame carriage members 5|. l the shaft projects below the cansupports 51 and is provided with a laterally extending wing ||2 arrangedto be so positioned that when a can is on the carriage, the wing ||2will effect the 1 opening of the valve for controlling vthe passage offluid to the nozzle over which the can 'is lo cated. The wing |2 isnormally held in inoperative position by means of a" spring ||3`attached at one end to an arm H4 fixed on the upper end of the shaft andat its other end to a pin 280 projecting from the top plate |30 of thecarriage. iAs a can is pushed to position over the supports 51, thecontact of the can with the arm ||0 will rotate shaft from the positionshown in full lines in Fig. I8 to that shown in dotted lines, and aslong as the can remains arriage, thev valve-V in itscompartment on theactuating wing l I2 will rema n in operative position. In this position,the wing |Iv2 will', during pauses in the rotary movement of thecarriage, be located over the end of an arm ||5 projecting inwardly froma hub ||1 pivoted in lugs H8 on the outer wall of each of the tanks 29to 33, inclusive. The hub ||1 from which the arm ||5 projects is alsoprovided with an inwardly projecting lug ||8 located above thevertically operating stem ||9 (Fig. 16) of a poppet valve |20 with whicheach of the several tanks vis provided. The valves remain normallyclosed until the stems ||9 are depressed by means of the lugs ||8, whichare forced downwardly when the arms ||5 are depressed bythe wings 2 onthe descent of the canv carriage.

rSince a wing ||2 located below a can compartment will be only invertical alignment with an ||2 will 4not be in position to operate thevalves.

The valves of the three first nozzles 34, 35 and 36, are each located,respectively, in one of the lhorizontally arranged pipes |2| positionedin the rects against the inner surfaces of the can a spray of cold waterreceived from a main ||9a with which the flrst pipe |2| is connected.The main ||9a may receive water under pressure from any source ofsupply. T'he water directed against the can falls into the tank 29 fromwhich it is discharged through an outlet pipe 300 into a sewer or other'convenient receptacle.

Each of the pipes |2| is provided with two upwardly extending branches|22 (Figs. 6 and 1| connected with one ofthe series of nozzles |23 whichspray the inside of the can covers simultaneously with the spraying ofthe cans.` The inner sides 'of the vertical portions of the branch pipes|22 are provided with a line of perforations, as shown in Fig. 16, todirect diverging sprays of cleansing fluid against the outer surfaces ofthe cans. Each pipe |2| is also provided at its inner end with avertically-extending perforated pipe i |24 which directs its spraythrough the slot 6| in the rear plate of the can compartmentv againstthe inner face of theoutside of the can. The cylindrical outside oi! thecan being thus sprayed from three points is thoroughly cleansed. Thedrip water from the outside of the can over nozzle 34 also falls intotank 20 and goes to Waste through opening 300.

After the can has been given the preliminary 1 rinse by the nozzle 34 itis carried upward, and then by a rotary movement of the carriage isbrought to position above the next nozzle 35. The

carriage then descends to lcause the nozzle 35 to project into the can.Nozzle 35 and the spray pipes |22' and |24 associated therewith directhot water against the inner and outer surfaces of the can, the-supply ofhot water for this nozzle and its associated spray pipes being receivedfrom the .tank 32 through the overflow pipe |3|.`

The hot water is forced through the nozzle 35 and pipes |22 and |24 by apump |32 diagram.

matically illustrated in Fig. 6, whichis connected with the pipe |2| intank 30 by pipe |33., The

pump receives the water from tank 30 throughwith the nozzle 36 throughthe pipe |46 which is an outerextension of the pipe |2| in tank 3|.While the nozzle 36 is spraying the inner surfaces of the can withsolution the outer surfacesare also sprayed with solution by the pipes|22 and |24 associated with nozzle 36. In making up the solution in tank3| at the beginning of the days run, water may be admitted into the tankfrom themain ||8a through the valve-controlled pipe 2,054,293 |41connected therewith, and from time to time during the day, the supply ofsolution in the tank 3| is replenished so that the strength of thesolution used is relatively uniform. The solution in the tank 3| isheated by a steam nozzle |46 connected to a steam main |4| by the pipe|49. The drippings from the inner and outer surfaces of the can overnozzle 36 fall into tank 3| to be used over again. To prevent the tank3| from overflowing it is provided with the hole 302 .leading intotank`30.

The can is next carried to position over thel nozzle 31 from whichitreceives an internal hot water rinse. Hot water is supplied to thenozzle 31 by heating clean cold water which is intermittently suppliedthrough a pipe |36 to a supplemental chamber |36 located in the tank 32and formed bythe partition |34. connected through a valve 31 with thecold water main |9a. Valve |31 is located in the tank 3| and is operatedby a lug |33 projecting from the hub ||1 of the valve-operating devicefor the valve |20 located in that tank. Each time the valve-operatingmechanism for the nozzle 36 .is operated, a supply of cold water isdelivered into the compartment |35 and is heated and discharged throughthe nozzle 31 against the inner surfaces of the can. The hot waterdischarged through the nozzle 31 is caught in the tank 32 and flowsthrough the pipe |3| into ltank 30. The cold water delivered into thecompartment |35 by the pipe |36 is heated by being drawn through,

the outlet |30 into the pipe |40 into which live steam is fed from thesteam pipe yi 4| having a branch |42 connecting with pipe |40 throughthe valve |20. Thenozzle 31 is connected with the pipe |40, as isa'vertical pipe |43 which has.

its upper end connected with one of the coverspraying nozzles |23, asclearly shown in Fig. 1.

The nozzle 38 subjects the inner surfaces of the can to thev action oflive steam to kill any deleterious micro-organisms adhering thereto.Nozzle 30 receives steam from the steam supply pipe |4| through thepipes 25| and. 252, with which latter pipe it is connected under thetank or drip pan 33. and is controlled by its respective valve |20. Tothe pipe section 252 is connected the lower end of an upright pipe 250connected at' its upper end to a cover cleansing unit |23. The nozzles30 and 40 direct a blast of air into the can. Neither of these nozzlesis controlled by a valve. A blower or other source of continuous air'blast causes a stream of air to issue from the nozzles to rapidly andeffectively dry the can as it is brought down over them. i

On the descent of the carriage to position the can over the second airnozzle'40, one side of the mouth of the can is brought into contact withthe upper end of a fixed projection or post |50 located behind andrising higher than the nozzle 40. As the descending can strikes thisprojection it is caused to tilt or incline` outwardly away from thecarriage and to fall against an abutment |5| having a curved upper endover which the can somersaults to land upright, with its mouthuppermost, upon the discharge platform |52, as shown in Fig. 8; Thedischarge platform |52 is supported on a frame composed of four shortuprights or legs 235 braced by horizontal angle-irons 266. To preventtoppling of the can as it strikes the platfonn, guard plates |53 and |64are provided along two sides of the platform. After the can comes torest in uprighted position on the platform it receives its cover, and isthere Trails |56 and |51, supported by a fixed j said frame beingcarried from aisupper ba`r`j|60 which extends out from the upperbars-128a of the stationaryframe of the machine. The rails` |56 and |51extend downwardly at an oblique angle toward the can carriage and are sospaced' that the cylindrical neck portion |6| of a/can" cover is..receive`d between them, and thef'langed top portion |62 of the coverrests ori the rails.

A guide plate 281 (Figs. 9 and 10)supported by brackets 288 extendingfrom a cross bar 289 connecting the vertical bars |58, prevents thecovers from rising from the rails |56 and |151. When a can is placed onthe platform |00.'e a cover is placed on the rails |56 and |51v and itslides downwardly thereon until it is held bya linger Y |63 projectingupwardly from one end of a rocking lever |64 which isgentrallypivoted at|65 in 'a bracket |66 extending downwardly from the rail |51. 'I'he rail|51 is provided with two spacedj apertures |61 and |68, that shown at|61 being adapted to permit the passage of the linger |63 through it toenable theilnger to engage the edge of the ange |62 of the cover andprevent the cover from sliding off the ends of the rails |56 and |51.Aperture |68 permits the upward'projection of a second finger |68located at the other end of the rocking lever |64. At the proper time,thero'cking lever |64 is Vswung on its pivot, to lower ilnger "|63 outof the path of the cover, permitting the cover to slide from the railsl|56 rand |51 and fall into a holder or rack mounted on a strip |10located on theftop plate |80 of the car Each rack consists of an inner,upwardly projecting, bent rod |1| securedto a base plate |12, and a pairof spaced side members |13 having laterally extended upper ends |14against which vwhich it is brought into alignment on descent of thecarriage.

When the ringer |63 on the lever |64 is moved .down through the aperture|61, the other nger |69 is moved'upward .through the aperture |68 intolposition to engage the front edge ofthe next cover on the chute andprevent its Vfarther descent until the next rise of the carriage.

" A rack or holder for a cover is situated over;`

each of the,v can compartments on the/carriage so that as each can istransported by the carriage, f

it is accompaniedby a cover located in the rack above the can. 'As thecarriage descends to place the cans over the nozzles, the covers locatedin the racks are brought into horizontal alignment with thecover-cleansing nozzles |28, as shown in Fig. 16, so that a, can and itscover are always simultaneously cleansed by the streams from therespective can and cover treating nozzles. A i

When a can is first placed on theplatform preparatory to being slid inwardly' toward the carriage, acover is placed on the rails 'l |56 and |51 and the cover will slidedownwardly to the position shown in Fig.,9 with its ilange |62 engagedby the finger |63. Asthecanis moved vl0 can comes into contact lwith aplate |16 secured on th free. end of an arm |15 projecting frpm avertical'shaft |11 journalled at its lower end in -a bracket |18 (Fig.,17) secured to the. under side bearing extending from one of thediagonal brace members |590.. As the can strikes against the plate |16and swings the arm |15, l,the beginning of such movement being indicatedin dotted lines in Fig, 18, the turning of the shaft |11 causes an armsecured on the upper end of the shaft |11, to be swung inwardly, or tothe left when viewedlas invFigs. 9 and 12. lI 'he free end of the arm|8| is connected with one end of a link |82 the other end of which ispivotally connected to the upper end Aof an arm |83 projecting upwardlyfrom the -lever |64.` Through.

' this arrangement, the canl pushed along 'the platform to a position onits inner end, causes the cover-holding nger |63 to be moved downwardlyoutv of the aperture |61 so that the cover held thereby, as shown inFig. 9, will be freed and will drop intothe racklocated above thecompartment on the carriage into which the can has been moved.

A spring |90 is secured at one of itsends to an arm |9| on the shaft |11 and at its other end to a pin `|92projecting downwardly from the platform i'l |00. When the arm |04 isdisengaged from the shoulder |06, the spring |90 returns thecoverfeeding device to its initial position, this action causing theilnger |69 to be lowered out of the aperture |60 so `that the coverengaged by it is l permitted to slide downwardlyv along the rails |66and |61 until it is stopped by the' finger |63 which is then extendingupwardly through the aperture I 61. When the nexty can is placed on theplatform and is siid'toward the carriage, it will strike the plate |16on the arm |16 and the next rcan cover then held by the finger |63, willbe released, permitting it to fall into the rack then positioned belowthe rails |66 land |61, inthe manner just explained.

As a can is ejected from the carriagefand uprights itself onto thedischarge platform, the cover which was located in the rack above thecompartment in which the can was located,` is also ejected from thecarriage. As the cover to be ejected from the carriage is being carriedtoward the discharge platform, while the carriage is in its elevatedposition and is being rotated, the top of the cover comes into contactwith an angular endpiece or plate |90 located on the end of an arm |94which is hinged at |96 on the frame member 26. 'I'he arm |94 is normallydrawn toward the discharge platform by a spring |96, its movement`toward the discharge platform being limited by a laterally extending pin|91 held in contact with 40 an abutment |99 ilxed to the frame member|60.v

As the carriage descends, the cylindrical portion |6| of the cover isbrought to yrest on a bar 200 connecting the upper ends of two rails 20|which are supported at the two ends of vertical struts 5 202 extendingdownwardly from the upper frame member |00. As the carriage continuesits` descent, the cover, left with its cylindrical portion resting onthe bar 200, is tilted outwardly by the pressure of the plate |93 underthe impulse of 50 the spring |96 and falls toward Vthe rails 20| whichare spaced suiliciently apart to receive the cylindrical portion ofthecover between them. The flange |62 of the cover resting von these rails,permits thecover to slide down and come to rest 55 on an inclinedsupporting plate 204 extending' inwardly from a ilxed upright 206. Anupper guide plate 206 serves to guide the cover 'to its proper positionof rest on the supporting plate 204, the cover being brought to-` a stopon the 00 support 204 by the rounded edge of a stop plate 201 againstwhich the cylindrical portion of the cover abuts, as shown in Fig. 8.

The vertical frame upright 206-is secured near its lowerl end to thedischarge lplatform frame 65 braces 206 and at its upperend it isrigidly braced from the frame member |60 by diagonally extending braces290. i x

As a cleansed can is moved laterallyon the platform toward the rollers'|66 to be carried away 70 thereby, or to` the righ`t in Fig. 6, thecleansed cover resting on the plate 204 is slid sidewise from the plateso that it `mns into the mouth of the Vcan just as the can is moved ontothe rollers |66. In this manner, the cleansed can and cover are 75carried away together. 'Ihe can is (moved,` laterb accesos ally fromthedischarge platformA andonto the rollers |66by means of a rotating arm2|0 (see Figs. 7 and 8) secured on a shaft 2|| mounted to rotate inbearings 2| 2 and 2|0 secured on the brace 209 and upright 206respectively of the frame of the machine. Attached on one end of theshaft 2|| is a sprocket 2 |4 over which a. drive chain 2| 6 passes. Thechain 2|6 also extends over an upper sprocket 2| 6 secured on the end ofa shaft 2|1 which is mounted at one end in a bearing 2|0 located at theupper end of the strut 206 and near its other end in a bearing 223 onthe cross brace 46 (Fig. l). The-chain`2l6 also engages witlra third4sprocket 2|9' secured on a short shaft 220 mounted in a bearing 22| onthe upright l206. lAt its inner end, the shaft220 carries acover-shifting arm 222 which is adapted to strike against and slide thecovers from their position on the plate 204 to cause them to fall intothe mouths of the cleansed cans as the cans 1 are moved by the arm 2|0from the discharge platform toward the rollers |66. The inner end of theshaft 2|1 carries a bevel gear 224 which meshes with another bevel gear226 secured on the end of the vertical shaft 4|. Through this,

arrangement, the vertical shaft 4| drives the shaft 2|1 which drives thechain 2-I6 so that the arms 2|0 and 222 will simultaneously engage andmove a cleansed can and a cleansed cover toward the rollers |66, thecover being `pushed from the plate 204 by the arm 222 and falling` intothe mouth of the can so that the can carries the cover away with it. i

' To permit the can-shifting arm 2|0 to engage the sidevof a can restingon'the discharge platform |62, the bottom of the platform is cut away orslotted at 226.

Briefly, the operation of the machine is as follows:

A can to be cleansed is placed on the entrance platform |00 by anattendant stationed at that point, but before the can is shoved into.the machine the cover for the can is placed on the cover chuteconsistingof the rails |66 and |61. If therev is no cover already -onthe rails, the cover placed thereon willslide down to the position shownin Fig. 9. If a cover is on the rails, it will be located in theposition shown in Fig. 9, and

the second cover placed on vthe, rails will be .l

located behind it. As the can is slid along the platform toward the can`carriage, its mouth will strike against the stop |02 unless the'carriageis in its lowered position and in readiness ito receive the can. Ifthecarriage is not in its lowered position, the attendant will make noeffort to push the can past the stop |02 until the carriage descends.Upon its descent ne ofthe can-supporting bars 61 will strike theolf-setarm |01 of the stop lever |03 so that the stop |02 will bedepressed out of the path of the can permitting the can to be slid in onthe narrowed end |0| of the platform. As the can is moved past the arm y|16, said arm will be swung to the left when viewed as in Fig. 18, thiscausing the roci'ing lever |64 to withdraw its nger |63fbelow` theaperture |61 and permitting the cover -restrained by the finger |62 tofall down into the rack over the a compartment in which the can' then onthe inner end of the entrance platform is situated. Whenvv the can ismoved toward the inner end |0| of the entrance platform, the side ofthecan contacts with the arm |0 and swings ittoward the back of the cancompartment tothe position shown in dotted lines in Fig. 18, which movesthe valveoperating wing ||2 to operative position, as

riage, upon rising, lifts the can from the inner end of the entranceplatform and carries it upwardly, and at the end of the upward verticalmovement of the carriage, the carriage is then rotated a step in aclockwise direction (when viewed inplan) and pauses in its rotarymovement with the can located above the first nozzle 34. The carriagethen descends so that the nozzle .34 is projected upward into the can.

Upon the descent of the carriage, the valve operating wing ||2, beingheld in operative position by the can, strikes the valve lever ||5 whichcauses the valve lug ||0 to depress the stem I9 of the valve |20 so thecold water is ejected from the nozzle L34 to wash the inner surfaces ofthe can. At the same time water is ejected from the vertical portions ofthe pipes |22 and the portion |24. and also through the cover-washingnozzle |23 which sprays the inner surface of the cover substantially asshown in Fig. 16, which also shows how the outer surfaces of the can arewashed simultaneously with the spraying ofv the w inner surfaces by thenozzle'34. A cylindrical defiector plate 299 (Figs. 1 and 8) extendsupwardly from the top plate |30 in back of the cover racks so thatfluids discharged from the cover-cleansing nozzles will be .directeddownward into the tanks below the nozzles. The carriage next rises `andupon doing so, the valve |20 is closed. cutting off the flow of waterthrough the nozzles 34 and |23 and the spray pipes connecting thesenozzles. When the' carriage reaches its raised position it again rotatesa step to bring the can above the next nozzle 35.' The carriage thendescends` and the can is'there sprayed inside and outside with hot waterwhile the cover is likewise sprayed.

The travel of the carriage continues in this way, bringing the can fromone nozzle to the next and subjecting it to cleansing and sterilizingtreatments, until the can reaches the air nozzle 39 where it is dried bythe blast of air therefrom. The second air nozzle 40, located inregi/s-l tration with the discharge platform, also directs a blast ofair on the can as the can is being ejected. When the carriage iinallyreaches a point with the can located above the nozzle 40 and descends,the mouth of the then cleaned and can is being discharged, thecover-ejecting elements |93 and 200 causing the cleansed cover to cometo rest on the plate, 204, as shown in Fig. 8. The arm 2|0 is then movedup through the opening 226 in the discharge platform and itstrikes-against theside of the cleansed and uprighted f can, forcing the camonto the rollers which 1 carry itaway. While the can is being slidtowardA the rollersv |55. by the arm 2|0. the cover-shifting arm 222strikes-.against the ilange Vof `the cover supported on the plate 204and slides the cover yfrom o the plate 204 so Vthat the cover dropsdownv into the mouth of the can f and is ycarried away by the can.v f

The actionof the machine is completely automatic, the attendant merelyplacing cans tobe cleansed on the entranceplatform, and at the proper.time sliding-them toward the inner end I of the platform, at the sametime placing` the y covers on the rails |56 and |51. When the cleans.ing operations are completedthe cans with their.v

. respective covers are discharged from the machine and carried awaytogether.
